The Role Of Nitric Oxide Dysregulation In Tumor Maintenance, Christopher Rabender
Theses and Dissertations
The inflammatory nature of the tumor microenvironment provides a cytokine and chemokine rich proliferative environment. Much of the responsibility of this environment is due to the production of Reactive Oxygen Species (ROS). These studies examined the proliferative rich tumor environment from a new perspective of Nitric Oxide Synthase (NOS) dysregulation. NOS’s have the ability to become uncoupled and generate superoxide in lieu of nitric oxide (NO). A requirement of NOS for the production of NO is the cofactor tetrahydrobiopterin (BH4) and when it is missing NOS becomes uncoupled and turns into a peroxynitrite synthase. Here I demonstrate that NOS is …
